• LT4430 Compensation Network

    Hello,

    I am using LT4430 in a new power supply design.

    I am designing a Fixed Input-Variable Output Flyback where duty varies from 25% to 75%.

    I would like to use LT4430 to drive the optocoupler but I can't figure out how I can choose components values…

  • LT8310 and LT4430

    Hello everyone,

    I am using the LT8310 and the LT4430 for an isolated 12V power supply. Input voltage is 24V. My setup is very similar to the one on page 33 in the datasheet, except for the transformer ratio - here I am using 1:1. With no load applied…

  • RE: LTC3803 isolated DC/DC

    Hi,

    The problem may be with feedback circuit TLV431. We don’t know if that circuit will work or what the problem is. We recommend using LT4430 for feedback as shown on page 13 of LTC3803 datasheet.

  • RE: LTC3803 soft start issue

    Hi Ken:

    If this is isolated application and you are using OPTO feedback circuit the soft start should be implemented on the secondary side. We have LT4430 part that addresses that issue.

    The internal soft-start should be adequate for non-isolated application…

  • RE: How does LT1431 work? how can I get the transfer function of LT1431?

    Beyond the three transfer functions graphs on page 4 and 5 of the LT1431 Data Sheet, there is no additional information available. You may also be interested in looking at the newer LT4430 Secondary-Side Opto-Coupler Driver.
